Metallic Viscous Filter/ Wire Mesh Filter
Metallic viscous/Wire mesh filter are pre filters that are designed for general ventilation and air conditioning system applications as well as for electric motors and plenum air for working areas. These are an economical and a very durable option over other pre filter counterparts.
Construction: The element is constructed using 5 layer of GI Wire mesh interspaced with 2 crimpled layers and 3 flat layers. The media is supported with expanded metal from both sides as reinforcement and housed usually in deep metal frame (custom build sizes are also available on order).
Standard metallic viscous filters have an efficiency of 65% for 20 micron size particles. Metallic filters with an efficiency rating of 65-85% to capture 25 micron to 50 micron size particles are also available on order. Efficiency can be increased to 85% if the filters are oil wetted.
Frame Type : Available in Flange or Box Type GI,AL.,SS.
Filter media : GI/SS/Aluminum expanded mesh
Face guard : Filter is protected with expanded mesh on both sides
Pressure drop :Initial pressure drop ~1mm wg & recommended final pressure drop is 5-10mm wg
Filter can withstand temperature >80âºc and relative humidity of 70%. Recommended air velocity is 2m/sec to 2. 5m/sec. Filter is washable and can be washed using water or back air pressure and reused.
Metallic filters are most suited for:
Air Handling Units (ahus),
Automatic Drain Holes,
Miscellaneous Industrial Ventilation.
